Beyond the Nitrogen Rate with Dr. Mike Castellano and Dr. Andrew Margenot
Sean and Andrew are finishing up their conversation about nitrogen with Iowa State University’s Dr. Mike Castellano and the University of Illinois Urbana-Champaign’s Dr. Andrew Margenot. This time, they’re focusing on how you can manage nitrogen on your acres to achieve high yields, reduce environmental impact and improve your bottom line. The crew discusses: ✅ How to be stewards of the land while chasing high yields ✅ Understanding nitrogen availability throughout the growing season ✅ Trials you can do on your acres to expand your farm’s database ✅ Replenishing the nutrient pool in your soils ✅ Ideal nitrogen timing and application rates across the Midwest 🌱 Meet the Guests: Originally from Rhode Island, Dr. Mike Castellano obtained his Ph.D from Penn State in soil science. He now is an agronomy professor at Iowa State University, where his research focuses on biogeochemical cycling and transport within the soil as it extends to the atmosphere and subsoil. His ultimate objective is to maximize sustainable productivity of agricultural systems, specifically looking at nitrogen. Connect with Dr. Andrew Castellano on LinkedIn. Dr. Andrew Margenot is originally from Rhode Island and earned his Ph.D in in Soils and Biogeochemistry from the University of California Davis. He is now an associate professor at the University of Illinois Urbana-Champaign, where his work addresses the literal foundation of all cropping systems: soils. Alongside his team, he evaluates how human activities can enhance or compromise soil services to human societies, with an emphasis on food security from urban and rural agroecosystems in the U.S. Midwest and East Africa.
